This is level 4 and for those interested in this type of puzzle you will stop using it once you know how it works. The quality is what you'd expect from Hanayama, although in this case I'd say the tolerances are a bit tighter, making the puzzle easier for some and more difficult for others. As this is a puzzle I would suggest the harder it is the better in the interest of the person solving it so as usual the assembly tolerances should be tighter. Over is a nice compact gift, especially for the price. However, if you solve puzzles on a daily basis, it might not be that interesting.
